Hi Sebastian.

(Sorry for the delay.)

None of both give me crackling.

The first one clearly gives me crackling, the second one does not.

No difference.

This does not work:

32,depth=3D32" ! alsasink device=3Dhw:0

Ditto:

32,depth=3D32" ! alsasink device=3Ddemix

Another thing that would be nice to try would be:

try with one of the pipelines above the have crackling to
set the buffer-time and latency-time properties of alsasink.

You can do so by writing instead of "alsasink"
"alsasink buffer-time=20 latency-time=1"

Try using higher values than these and please report if this makes
any difference.

Thanks

Also please try if using "alsasink device=hw:0" or "alsasink
device=demix" makes a difference.

And I guess
gst-launch-0.10 audiotestsrc ! 
"audio/x-raw-int,width=32,depth=32" ! alsasink

gives crackling while
 
gst-launch-0.10 audiotestsrc ! 
"audio/x-raw-int,width=16,depth=16" ! alsasink

does not?

Or does

gst-launch-0.10 audiotestsrc volume=1.0 ! 
"audio/x-raw-int,width=32,depth=32" ! alsasink

give crackling while

gst-launch-0.10 audiotestsrc volume=1.0 ! 
"audio/x-raw-int,width=16,depth=16" ! alsasink

does not?

Nope, no crackling on any of those files. Neither created with the Unstable nor
with the Testing packages.

Great. Can you please test the following:

gst-launch-0.10 audiotestsrc num-buffers=1000 ! audioconvert !
"audio/x-raw-int,width=32,depth=32" ! wavenc ! filesink
location=test1.wav

gst-launch-0.10 audiotestsrc num-buffers=1000 ! audioconvert !
"audio/x-raw-int,width=16,depth=16" ! wavenc ! filesink
location=test2.wav

And then run
aplay test1.wav
and
aplay test2.wav
?

Do you get crackling on test1.wav too and not on test2.wav?

Yep, it=E2=80=99s exactly as you say. The second line gives the same outp=
ut as with the
Testing packages. So the change from 16 to 32 bit seems to be the right l=
ead.

Also, could you try:

gst-launch-0.10 filesrc location=/path/to/file ! decodebin !
audioconvert ! alsasink

and

gst-launch-0.10 filesrc location=/path/to/file ! decodebin !
audioconvert ! "audio/x-raw-int,width=16,depth=16" ! alsasink

(both in one line of course).

I'd assume that the first involves crackling and the second doesn't, can
you confirm that?

I did that including the output for the Testing packages for comparison
purposes. I canceled the playback a few seconds after the cracks appeared to
keep the logfile "small". (And approx. the same time for the Testing packages.)

Since my mail was rejected because of its size, you can find both logfiles here:

Hi,
can you do
GST_DEBUG=5 GST_DEBUG_NO_COLOR=1 gst-launch-0.10 playbin
uri=file:///path/to/file &> log

and attach the log (bzipped) to this bugreport?

After upgrading to the latest version playing any file results in cracks during
playback. Downgrading all gstreamer0.10 related packages to the Testing version
fixes this problem for now. I’m using a soundcard with the CMI8783 chipset.
